Quality, reliability and consistency for over four decades As an alternative and complement to our range of proven ceramic insulators, Lapp Insulators offers the Rodurflex advanced technology insulator system.today these composite insulators made of highgrade synthetic materials have exhibited outstanding mechanical and electrical characteristics, and have exceeded all overhead line and switchgear engineering applications in more than 50 countries worldwide. 1965 Development of composite insulators begins with a twocomponent system consisting of a rod made of fiberglass reinforced plastics (FRP) encased in a silicone elastomer housing. 1967 Suspension class Rodurflex production begins. 1974 Hydrolysis resistant resin system for a fiberglass reinforced resin rod is introduced. 1979 High temperature vulcanized (HTV) silicone rubber is introduced, improving the mechanical characteristics of the material. 1979 Sheath thickness of the housing is increased to 3mm to reduce electrical field strength within the FRP rod and provide better protection during handling and installation. 1982 Metastable silicone sealing system is developed to prevent moisture ingress to the FRP rod. 1983 Acid resistant glass fibers (ECR) are introduced to prevent brittle fracture of the FRP rod. 1985 Compression type, forged steel end fittings are introduced to improve the system s mechanical strength. 2001 Lapp Insulators purchases Ph. Rosenthal & Company the polymer insulator division of Germanbased CeramTec AG inventor of Rodurflex composite insulators, and a global leader in the production of lightweight silicone rubber polymer insulators. 2005 Lapp Insulators begins domestic production of Rodurflex high voltage composite insulators capable of servicing North American utility companies from its Sandersville, Georgia international distribution center.

Rodurflex Insulators are wellsuited for: High contamination applications Areas where vandalism is a problem High creepage on a short length Compact line applications Key Features Outstanding resistance to environmental factors such as UV light, ozone, acid, contamination and moisture. Interior tensile strength higher than steel, despite weighing approximately 75% LESS. Worldwide transmission system applications up to 765 kv. Reduced installation costs. No heavy lifting equipment required. High resistance to discharges and leakage currents. Reduced creepage requirtements for optimal performance when compared to porcelain, due to hydrophobic properties. Greater resistance to vandalism. High explosion resistance of hollow insulators in case of internal pressure buildup. 20 UP 24 TO INCHES FEET The Rodurflex design allows for infinitely variable section lengths & creepage distances for every product. Inside the Lapp Rodurflex System Waterrepellent, UV and coronaresistant silicone rubber base polymer housing. Premolded weathersheds are chemically bonded to the housing, eliminating moldlines and allowing variable creepage distances for a fixed insulator length. Metal fittings are fixed to the fiber glass core, not the silicone housing for maximum mechanical strength. Corona ring applied to the metal fittings to protect the housing. Housing is chemically bonded to the fiberglass core. Hydrolysisresistant resin system applied to the fiberglass reinforced resin rod. 3mmthick high temperature vulcanized (HTV) silicone rubber sheath improves the system s mechanical characteristics while reducing FRP rod s electric field strength. Also protects the FRP rod during handling and installation. Metastable silicone sealing system prevents moisture ingress to the FRP rod. 1
